Senior economic adviser to Barbara Boxer Marcus Stanley was arrested Tuesday entering the Hart Senate Office Building with a "substance that tested positive for marijuana," apparently jumping the gun on possible passage this November of Proposition 19 despite his boss’s opposition to the measure.

An aide to Sen. Barbara Boxer was arrested Tuesday and charged with possession of marijuana after he was stopped during a security screening while entering the Hart Senate Office Building in Washington at about noon.

Sgt. Kimberly Schneider, a spokeswoman for the U.S. Capitol Police, said officers observed Marcus Stanley, 43, with a “green leafy substance that tested positive for marijuana.” He was released later on Tuesday, she said. Stanley had been working for Boxer’s senate office since January 2009 as a senior economic adviser.

“Marcus Stanley is no longer with this office,” Boxer’s communication director Zachary Coile said in a statement. “He submitted his resignation and Sen. Boxer accepted it because his actions yesterday were wrong and unacceptable.”

Rachel Weiner at WaPo reports:

Because the charge was a misdemeanor, Stanley was released soon after being charged. He quit Boxer’s staff shortly thereafter.

Politico reports:

Stanley has worked on Capitol Hill since 2007, according to financial disclosure records from Legistorm, and draws a six-figure salary. He has also worked for the Joint Economic Committee.

Marijuana possession has been an ongoing issue on the Capitol grounds, especially since the Capitol Visitor Center opened with additional screening facilities. In the past year and a half, more than a dozen people have been stopped for bringing marijuana into the Capitol complex, along with other drugs, including at least one instance involving cocaine, according to police records….

This is not the first time a member of Boxer’s senior staff has been arrested. Senior policy adviser Jeffrey Rosato, who also worked on the EPW committee, was fired in 2008 after he was arrested and charged with the receipt and distribution of child pornography.

Stanley is the fourth Hill aide to be arrested by Capitol Police this year, according to an analysis by POLITICO.
